Sometimes things are not as they appear, especially when religion, magic, and shady dealings mix. It’s 1908, and itinerant spirit medium Madame Ilsa von Hoffmann is at the end of her professional rope, facing down two unappealing options: join an ill-conceived commune founded by some fellow trans ex-vaudevillians, or take on a high-paying but mysterious job offered by a religious extremist in Salt Lake City. Madame Ilsa opts for Utah and the employ of one Roger Marsh who, it turns out, wants her to summon the ghost of Joseph Smith, Mormonism’s founder, to give his blessing to Marsh’s fledgling offshoot of the mainstream church. Unsure how she’ll pull off this near-impossible task, Ilsa finds an ally in Francie Bream, an East Coast journalist in town to profile Mormon women at the dawn of the twentieth century. Bream’s motives remain obscure to Ilsa, though she begins to suspect the journalist has an agenda far more sinister than she could have imagined. Complicating the situation further are an inept and volatile henchman, a relentlessly orthodox Mormon apostle, a copper magnate with a fetish for polygamists, Marsh's rogue third wife, and a vengeful private investigator from Ilsa's past. As dead bodies accumulate around her, Madame Ilsa worries less and less about saving her career, and more about making it out of Salt Lake City alive.
